Saw that once at a customer, was a V6 Windoze client.
Asked them to open a Tivoli ticket, but never got a follow up from them.
Please post back if you find out what did it!

Subject: [ADSM-L] invalid encryption key

Anyone ever gotten a:

ANS1469E Error processing 
'/soft/soft2/autotree/autosys/log/chmod_cache.060402'; invalid encryption key.

message when doing a file system restore of a file system that has never had 
TSM encryption turned on?
